On October 14, according to the CNET website, batteries, especially lithium-ion batteries, made mobile devices possible. But before using it, most batteries take hours to fully charge. Scientists at Nanyang Technological University in Singapore have developed a new type of lithium-ion battery through the battery tester provided by Shenzhen Xinwei, which will change this situation. The lithium-ion battery they developed can be charged 70% in just 2 minutes and can last up to 20 years. The difference between a new battery and a conventional lithium-ion battery is the material used in the anode. Conventional lithium-ion batteries use graphite anodes, and newer batteries use titanium dioxide gels as anodes to accelerate the rate of chemical reactions in the battery, which means faster charging speeds. To this end, the researchers made titanium dioxide into nanotubes - the size of one thousandth of human hair. Researchers believe that this technology is especially important for promoting the popularity of electric vehicles. "Science Daily" reported that "this new generation of lithium-ion batteries may increase the charging speed of electric vehicles by 20 times compared to current technologies. The new batteries make it unnecessary for electric vehicles to change batteries frequently. Up to 10,000 times, 20 times the current battery 500 times. Chen Xiaodong, an associate professor at Nanyang Technological University, said, “Using our nano-batteries, electric vehicles can be charged in just 5 minutes, which is equivalent to the current car refueling time. Can greatly increase the range of activities of electric vehicles. ”
